Answer:

Option (d) is correct.

x=9

Step-by-step explanation:

Given : expression -5\sqrt{x}=-15

We have to solve for x.

Consider the given expression  -5\sqrt{x}=-15

Divide both side by -5, we have,

\sqrt{x}=\frac{-15}{-5}

Simplify, we have,

\sqrt{x}=3

Squaring both side, we get,

(\sqrt{x})^2=3^2

Simplify, we get,

x=9

Thus, Option (d) is correct.

A plumber has a 2.5 metre long copper pipe
Anastaziya [24]

We have an object measured in <u>Meters</u>, and we want to cut sections of it off in <u>Centimeters</u>, a different unit of measurement.

Because we're subtracting sections of the pipe, we want to make the units the same, this will make our calculations easier.

1 Meter = 100 Centimeters, so, <u>2.5 Meters = 250 Centimeters</u>

We're cutting ( 60 Cm + 35 Cm + 90 Cm ) off, which totals <u>185 Cm</u>.

250 Cm Pipe - 185 Cm Cuts = 65 Cm Pipe Left
